Shape analysis with overcomplete spherical wavelets

Yeo BTT, Yu P, Grant E, Fischl B, Golland P. Shape analysis with overcomplete spherical wavelets. Med Image Comput Comput Assist Interv. 2008;11(Pt 1):468–76.


In this paper, we explore the use of over-complete spherical wavelets in shape analysis of closed 2D surfaces. Previous work has demonstrated, theoretically and practically, the advantages of overcomplete over bi-orthogonal spherical wavelets. Here we present a detailed formulation of over-complete wavelets, as well as shape analysis experiments of cortical folding development using them. Our experiments verify in a quantitative fashion existing qualitative theories of neuroanatomical development. Furthermore, the experiments reveal novel insights into neuro-anatomical development not previously documented.
